Apparent Life-Threatening Events

2018

Objectives Apparent life-threatening event (ALTE) refers to a constellation of unexpected events suddenly occurring in infants that extremely alarm the observers. The objectives of this study were to evaluate 1) intervention of Emergency Service (ES) at home, 2) parental behavior before ES intervention, 3) patients' outcome at follow-up of a minimum of 6 months. Methods Retrospective study of infants younger than 12 months whose parents called ES and were evaluated for ALTE from 2005 to 2014. Tactile stimulation (TS) was defined as any maneuver performed by parents or ES staff aimed at rescuing patients without cardiopulmonary resuscitation attempts. Cardiopulmonary resuscitation was define…

Preoperative, Intraoperative and Postoperative Corticosteroid Use as an Adjunctive Treatment for Rhegmatogenous Retinal Detachment

2020

The treatment for rhegmatogenous retinal detachment (RRD) is surgery, including pars plana vitrectomy (PPV) and scleral buckling (SB). Despite surgical advances, degeneration of the photoreceptors and post-operative complications, such as proliferative vitreoretinopathy (PVR), often occurs as the result of inflammation, preventing complete visual recovery or causing RRD recurrence. There is increasing evidence that in the presence of RRD, the activation of inflammatory processes occurs and the surgery itself induces an inflammatory response. This comprehensive review focuses on the use of different formulations of corticosteroids (CCS), as an adjunctive treatment to surgery, either PPV or S…

Synaptopodin regulates denervation-induced homeostatic synaptic plasticity

2013

Synaptopodin (SP) is a marker and essential component of the spine apparatus (SA), an enigmatic cellular organelle composed of stacked smooth endoplasmic reticulum that has been linked to synaptic plasticity. However, SP/SA-mediated synaptic plasticity remains incompletely understood. To study the role of SP/SA in homeostatic synaptic plasticity we here used denervation-induced synaptic scaling of mouse dentate granule cells as a model system. This form of plasticity is of considerable interest in the context of neurological diseases that are associated with the loss of neurons and subsequent denervation of connected brain regions. In entorhino-hippocampal slice cultures prepared from SP-de…

Tibial tubercle osteotomy: effect of different osteotomy planes on contact surface area and tubercle anteriorization

2022

In 1983, Fulkerson introduced a technique of tibial tubercle osteotomy performed according to an inclined plane with respect to frontal plane. Due to obliquity of the osteotomy plane, this procedure allows both anterior and medial transfer of the tibial tubercle. The purpose of the study was to investigate the influence of the different degrees of the oblique plane of osteotomy on anterior displacement and the contact surface area of tibial tubercle. Synthetic bones were used for the study. An osteotomy of the tibial tubercle (TT) was performed in each specimen. Specifically, 3 different degrees of osteotomy planes relative to the reference frontal plane were examined: 20°, 30° and 40°. On …

Non-metallic implant for patellar fracture fixation: A systematic review

2016

Abstract Introduction Despite good clinical outcome proposals, there has been relatively little published regarding the use of non-metallic implant for patellar fracture fixation. The purpose of the study was to perform a systematic literature review to summarize and evaluate the clinical studies that described techniques for treating patella fractures using non-metallic implants. Methods A comprehensive literature search was systematically performed to evaluate all studies included in the literature until November 2015. The following search terms were used: patellar fracture, patella suture, patella absorbable, patella screw, patella cerclage. Two investigators independently reviewed all a…

Predicting Lung Deposition of Extrafine Inhaled Corticosteroid-Containing Fixed Combinations in Patients with Chronic Obstructive Pulmonary Disease U…

2021

Background: Functional respiratory imaging (FRI) is a computational fluid dynamics-based technique using three-dimensional models of human lungs and formulation profiles to simulate aerosol deposition. Methods: FRI was used to evaluate lung deposition of extrafine beclomethasone dipropionate (BDP)/formoterol fumarate (FF)/glycopyrronium bromide (GB) and extrafine BDP/FF delivered through pressurized metered dose inhalers and to compare results with reference gamma scintigraphy data. FRI combined high-resolution computed tomography scans of 20 patients with moderate-to-severe chronic obstructive pulmonary disease (mean forced expiratory volume in 1 second 42% predicted) with in silico comput…

Retinal vascular imaging in cardiovascular medicine: New tools for an old examination

2017

The old concept that the eye is the only window through which the body microcirculation can be observed in life easily, safely and repeatedly is part of the cultural baggage of every physician. When Hermann von Helmholtz invented the direct ophthalmoscope in 1850, he opened the door to a non-invasive visualization of human microcirculation in vivo at the retina. Only a few years later, the Scottish ophthalmologist Marcus Gunn documented the close association between retinal changes, and renal and cardiovascular diseases (CVD) in hypertensive patient. In 1939, Keith, Wagener, and Barker showed that the severity of retinal microvascular abnormalities was predictive of mortality in patients wi…

Lumican and biglycan expression in lungs of COPD patients

Utilizzo della valutazione della frazione di Ossido Nitrico Esalato (Fe NO) in pediatria.

Introduzione Il FeNO è stato studiato come marcatore di risposta per la terapia con steroidi inalatori (ICS) e come marcatore dell’effetto degli inquinanti sull’infiammazione delle vie aeree. Obiettivi di ricerca Il progetto di ricerca di Dottorato si è articolato in due linee di ricerca: (A) clinica: i) per determinare il valore del FeNO nel controllo dell’asma; ii) per esplorare il ruolo del FeNO come marcatore predittivo nella gestione della malattia; (B) epidemiologica: per esplorare il ruolo di determinanti ambientali sul FeNO. (A) LINEA DI RICERCA CLINICA Popolazione in studio: 56 pazienti con Asma Persistente (AP) valutati con prove allergiche cutanee, test clinico-funzionali, C-ACT/…
